摘要:
A method of protecting data stored in a memory of a welding controller provided with an EEPROM as a storage element capable of storing welding control data in a welding controller, thereby enhancing reliable protection of data stored in the EEPROM. The method of protecting data stored in a memory of a welding controller comprises the steps of providing the EEPROM having write validity control function means in the controller, using the EEPROM as a storage element for storing welding control data therein, writing the welding control data into the EEPROM and storing the same in the EEPROM, reading the welding control data from the EEPROM when the welding controller is used, and rendering the EEPROM transitive from a write disable state to a write enable state by the write validity control function when the welding control data is changed.

A welding system is capable of shortening length of connection lines and of effectively utilizing devices as a whole. The system includes a welding controller provided with an I/O interface, a controller unit provided with a programmable logic controller and connected to the I/O interface of the welding controller through a field bus interface serving as a communication link, a welding machine and general-purpose peripheral equipment. The welding controller controls the welding machine and the general-purpose peripheral equipment upon receipt of instructions from the programmable logic controller through the field bus interface.

A lens driving apparatus is disclosed. The lends driving apparatus may include a movable body holding lenses, a fixed body in which the movable body is mounted and movably along the lens optical axis direction, and a drive mechanism that moves the movable body in the lens optical axis direction. The drive mechanism may be equipped with a coil that is held by the movable body or the fixed body, a magnet that is held by the other body of the movable body and the fixed boy, and a regulatory means that regulates the movement of the movable body which is induced by an electromagnetic force generated when current is passed through the coil. The coil may be opposed to the magnet in the lens optical direction.

A cylindrical case provided with a chamber is coaxially attached to a rotary shaft of a motor. A plurality of balancers are movably provided within the chamber so as to cancel a rotation eccentricity of the motor. A viscous member such as high viscosity fluid is provided on at least one of the surfaces of the balancers and an inner face of the chamber.
